VEHICLE-HEATING DEVICE.

Specification of Letters lPatent.

lPatented Feb. 24,1920.

Application filed February 9, 1917. Serial No. 147,631.

To all 'whom t may concern:

Be it known that I, JACOB F. MA'rsoN, a citizen of the United States,and resident of St. Paul, in the county of Ramsey and State ofMinnesota, have invented certain new and usefull Improvements inVehicle- Heatin Devices, of which the following is a speci cation.

This invention relates to heating devices and has more especialreference to a vehicle heater. t

The invention has for its principal object to provide a novel heatingdevice for motor driven vehicles, whereby the interior of the vehiclebody will be heated by the exhaust gases from the engine and as aconsequence,

Vwill render the interior of the vehicle lbody :comfortable for theoccupants thereof.

It is a more specific object of the invention to provide a novel form ofexhaust manifold for the vehicle engine so constructed as to permit theiow of air therethrough, the air upon coming intovcontactwith the heatedarea of the manifold being heated in turn and then dischargedinto theinterior of the vehicle body.

Another object of the invention is to provide means for governing thepassage of air through the exhaust manifold, thereby 4allowing thetemperature of the interior of the vehicle body to be regulateda'ccordingly.

Among other aims and objects of the invention may be recited, theprovision of a device of the character mentioned with a view tocompactness, and in which the number of parts are few, the constructionsimple,

4the cost of production small, and efficiency of operation high. v

The invention conslsts, furthermore, 1n the novel arrangements andcombinations of the parts of the device as well as in the details of theconstruction of the same, all of which will be more fully described inthe following specification, and then iinallyembodied in the 'clauses ofthe claim which are appended to the specification and -which form anessential part of the same.

The invention is clearly illustrated in the accompanying drawings,- inwhich:

vFigure 1 is a side elevation of my improved heatin attachment asapplied to a fragment of t e conventional type of vehicle combustionengine;

` Fig. 2 is a longitudinal horizontal section therethrough taken on theline 2-'-2 of Fig. l, and,

Fig. 3 i is a vertical transverse section through the same taken on theline 3-3 of Fig. l.

Similar characters of reference are employed in all of the abovedescribed views to indicate corresponding parts.

Referring now to the several figures of the said drawings, it is to benoted that I have Shown for the purpose of illustration the presentimprovements as applied to the conventional type of multiple'cylindercombusltion engine, designatedin its entirety by the numeral 1. As willbe understood, thel engine l is mounted upon a suitable bed arrangedupon the chassis of a motor driven vehicle, a portion of the vehicledash board being fragmentally shown and indicated by the numeral 2. Withmore especial reference t0 .the present improvements, there is providedan exhaust manifold 3, which manifold is provided with a plurality ofports 4, these ports in turn being connected to the outlet or exhaustports of the various cylinders of the enginel, while the outer orremaining end of the manifold is provided with an externally screwthreaded nipple 5 adapted to be engaged with a suitable gas receivingand discharging means. As will be noted, the upper portion of themanifold 3 is enlarged and has its top surface flattened as at 6, onwhich a `plurality of longitudinally extending heat radiating webportions 7 are formed, the oppositely. disposed faces of the outermostweb portions being beveled for a purpose which will be subsequentlyapparent.

A housing element 8 is arranged over the flattened top` surface 6 of themanifold 3 and has its respective top portion arranged in spacedrelation from the upper extremities of the Various longitudinallyextending web portions 7. To secure the housing element 8 vin positionupon the manifold 3, set screws directed in parallel relation and thatthe4 housing is U-shaped transversely and attached by its edges to theparallel portions of the manifold. Upon the inner face of the topportion of the casing member a plurality of diagonally disposed baieplates 10 dium of a plurality of rivets'll 4or the likeV the casingmember 8 into the vehicle body,

'tudinally extending web portions 7, the

are arranged. the said baiiie plates being secured in position thereonthrough the mewhich are passed through the same into engagement with theadjacent portions of the, Obviously, bybeveling.

casing member top. the opposite faces of the outermost longisides of thecasing member 8 may be readily placed over'the same and engaged with thesides of the manifold 3 with but little effort. Each of the ends of thecasing member 8 are opened, but, as will be noted, one of the "endsthereof is reduced `asv at 12. Between the side walls ofthe reducedportion 12, is a regulating door 13, having the opposite side portionsthereof flanged and apertured hereby a pivot bolt 14 may be passedthrough the same and into engagement with the adjacent portions of thesaid side walls. of the lip portions.. The regulating door 13 is snuglyarranged in the open-- ing in the en d of the exhaust manifold 3 andwhen swung into its uppermost position will serve` to prevent thepassageof air from since, asis shown '1n Fig. 1, a portion of the said reducedend of the manifold 3 is passed through a suitable opening formed in theVehicle dash board 2 into the body there of. With the door in itsuppermost 'posi tion the air passing through thecasing 8v will beshunted through the lower porti Jn of the openingl of the reduced end12.

Hence, by varying the position of the door 13 the amount'of heated airdirected into the vehicle and the amount directed therefromv may becontrolled. Asv means for maintaining the'regulating door 13 in4 itsvarious adjusted positions, a' locking pin 15 is slidably arranged upona suitable bracket carried thereby and is normally held extend! .ed bvmeansof an expansible coiled spring 16 arranged thereabout;` and bearingupon one 4face of the said bracket member.` A cotter pin or like deviceis' engaged with the pin 15 adjacent the remaining extremity of thecoiled spring 16 and as will be understood, permits the spring to bearthereupon. A plurality of recesses or pockets 17 are formed 1n certamofthe Side walls of the lip portions 12 in the form of an arcV and are soarranged to receive the free extremity of the locking pin therein, Ahandle 18 may be and preferably-is arranged upon the outer face of theregulating door 13 Aand serves 'for an obvious purpose:

In'operation, the exhaust'manifold 3 vwill byv reason of the passage ofthe heated exhaust gases be heated to a high degree of'temperature andwhenl the regulating door 13 has been opened sufficiently, a draftthrough the castherthrough from the engine 1.

the casing member 8, `the diagonally disposed baile plates 10 areprovided and serve to deflect the same downwardly onto the Ah e`:t'radiating web portion 7 and also to delay the passage of the sametherethrough materially. lBy moving the regulating door 13, to itsuppermost position, the passage of body will be discontinued, inasmuchas it will be shuntedgthrough the lower portion of the opening of thereduced end 12.

'i *I am aware'that changes may I,be made in th'e'various arrangementsand combinations of parts as well as in the details of the constructionof" the' same, without departing from A the scope of my presentinvention, as defined Ain thev appended claims; hence', I do not limitmy'invention to the exact arrangement and' combinations of the devicesand parts as-illustrated inthe accompanying drawings, andas described inthe accompanyings-pecilication, nor do I confine my* self to theexactdetails of the constructionl of the said parts.

I claim 41. In a motor, hood open at the ends and connected to the sidesof the manifold and operating to conline the. heat radiated therefrom, apluralit'y of transverse baille devices attached to the upper wall ofthehood anddirected toheated air into theyinterior of thev vehicle ward themanifold, and a damper within r the outlet end' ofV the hood to controlthe direction of the air currents as they exit i from the hood. 1

v 2. In a motor, an exhaust manifold having its side faces in parallelrelation, a hood U- shaped transversely open at the ends and connectedby its side edges to the side faces of the manifold and operating tocnfinel Vthe heat radiated therefrom, a plurality of transverse bailledevices attached to the upperwall of the hood and direc-ted toward letend of the hood to controlthe direction the manifold, and adamper/within the outof the air currents as theyexit from the hood.

In testimony whereof,I affix mysi'gnature hereto. t f
